-====== Product Announcements ​ - August 12, 2010 ====== 
  
-We're constantly working to improve our products and roll in various requests from our users. ​ This page will contain some updates on what we're spending our time on. 
- 
- 
- 
-===== Release date ===== 
-I know the first question coming is "​when"​. ​ As soon as we know, we'll post it.  I promise. ​ I'd rather wait until we are sure about a release date than to keep posting made-up dates and missing them.  The very minute we feel comfortable enough with a release candidate to schedule a date, we'll post it up.

-===== Individual deadtime controls ===== 
-With the release of [[v3firmwarechangelog|3.20.174]],​ we have finalized the individual deadtime controls function. 
- 
-If you're not familiar with this, we have a video up of some [[http://​www.youtube.com/​user/​ecmtuning#​p/​a/​u/​1/​cO7fPmAxG50|sample results]]. ​ Basically, you can dial in different deadtime values for each injector. ​ This lets you fine tune the behavior of injector sets that aren't match perfectly at idle pulsewidths. ​ Most places are not able to properly test injectors with our ECU drivers and at our typical idle pulsewidths. ​ So while the injectors they ship may be well matched at 100%, 80% or even 20% duty cycle, they can still be VERY different at idle due to variations in deadtime from one to the next. 
- 
-In addition to controlling individual deadtime, we have increased deadtime resolution as well.  The factory 1G ECU runs with a resolution of 24usecs and the 2G runs with 15usecs. ​ In previous releases, ECMLink normalized these so that both are 15usecs, but even this can be too coarse for large injectors. ​ Running 1750s with 15usecs "​jumps"​ in injector pulsewidth at idle is just too much. 
- 
-We have increased this resolution to 1 usec (!!) to match the code inside the ECU (hardware limitations still limit this to 4 usecs, but the code tracks pulsewidths down to 1 usec for increased precision). ​ Doing so makes for much nicer idle quality with large injectors. 
- 
- 
-===== Boost controls ===== 
-With the release of [[v3firmwarechangelog|3.20.245]],​ we have finalized our gear-based boost control implementnation. 
- 
-Yes, after many requests we have finally added [[boostcontrol|boost control logic]] inside the ECU.  This has been a requested item for *years* and we're sorry it has taken so long to finally free up the time to work on it.  But it's done now, so enjoy! 
- 
-The functionality is modeled after the stock Lancer EVO code, with a few tweaks of our own thrown in.  It's basically a full gear-based solution with error correction/​learning built in.  And unlike the current EVO version, we'll support any number of boost sensors with a simple drop down selection. ​ We also have an "​[[bcssetup|auto adjustment]]"​ tool to make it painfully simple to dial in.

-===== 2G DSM non-EPROM conversion ===== 
-{{http://​www.ecmtuning.com/​images/​photos/​noneprom2g.jpg?​95x100 ​ }}Yes, we're finally nearing completion of this project. ​ We've had the 1G DSM non-EPROM conversion out for a while, but the 2G version was really MUCH more difficult in terms of both design and fabrication. ​ Unfortunately,​ I don't expect we'll be able to offer this conversion at the same price as the 1G.  The component costs are just astronomical. ​ But, we're at a point where it doesn'​t make sense to halt the project, so we'll push it through and when someone really needs it, we'll be able to help them out.

-===== Native 2G MAF connector ===== 
-{{http://​www.ecmtuning.com/​images/​photos/​2gmafconnectors.jpg?​200x130 ​ }}IMO, this is one of the coolest things we've done in a long time.  It seems so simple at first, but nobody else in the world has this wire-side connector. ​ We had to custom design, prototype and mold this piece ourselves. ​ It's basically the mating piece to the 2G MAF connector on the car's wiring harness. ​ It's a properly sealed solution that doesn'​t exist anywhere else. 
- 
-We will be using this connector on our GM MAF adapters to finally provide a true plug-n-play solution for 2G DSMs.  The 1G guys already have this because their mating connector already exists. ​ We're finally catching the 2G guys up.  :-P 
- 
-Prior to this connector we (and everyone else) had been using a Delphi equivalent that just happened to sorta shove into place but was seriously lacking in a number of ways including the lack of a locking tab, improper fit and no sealing mechanism at all. 
- 
-We may even start providing plug-n-play SD harness conversions too.  Not sure on that one, though, because the cost gets a little crazy when you consider that we have to incorporate a buffer board of some sort at the same time due to [[2gbaroinputworkaround|compatibility issues]] with the 2G ECU's baro circuitry.

- 
-===== Quick-connect ===== 
- 
-One of the next items on our to-do list is a quick-connect feature to provide for near instant connect speeds with the ECU by caching configuration data on the laptop. ​ The application will always know whether its cache of data matches the ECUs by a complex checksum algorithm. ​ But details aside, the idea is to reduce that lengthy configuration read step to near zero. 
- 
- 
- 
-===== Live edit ===== 
- 
-You can already do live changes (while the engine'​s running) to most configuration settings in V3.  Everything in the ECU Config tab can be changed at any time.  That includes the RPM-based fuel and timing adjustments,​ airflow compensation,​ speed density VE table, etc., etc. 
- 
-You can even have the application auto-save the changes as you're making them!  It's like having a dial control for any configuration value in the ECU Config tab.  Check the "​auto-save"​ box, select a cell or range of cells and then use the Ctrl+up/​down arrow keys to changes values in the ECU instantly. ​ 
- 
-Direct Access changes require the engine be stopped, however, because the ECU has to go into a reflash mode to save those changes to code space. ​ This isn't a major problem because most changes to direct access tables require time to review and tweak anyway. ​ The things that respond well to instant edits can already be edited at any time on the ECU Config tab. 
- 
-But we're always looking to improve things, so we're going to try out a system to allow for instant edits of direct access tables as well.  We'll keep this page posted with results and progress.
